The heating module 2500 covers the regeneration area of ​​the moisture-absorbing and dehumidifying member 2200 (moisture-absorbing and dehumidifying turntable 2201) and is used to heat the regeneration area of ​​the moisture-absorbing and dehumidifying member 2200 (moisture-absorbing and dehumidifying turntable 2201) and dehydrate the moisture absorbed by the moisture-absorbing and dehumidifying member 2200 (moisture-absorbing and dehumidifying turntable 2201). The condensing module 2600 is used to condense the dehumidified flow flowing out from the regeneration area of ​​the moisture-absorbing and dehumidifying member 2200 and dry the dehumidified flow.

[0072] According to some embodiments, the drying apparatus 2000 further includes an upper housing and a lower housing. The upper and lower housings cover and secure each component of the drying apparatus 2000, forming the drying apparatus 2000 as an integrated module.

[0073] According to some embodiments, the upper and lower housings of the drying apparatus 2000 may be separate housings corresponding to a single component of the drying apparatus 2000, or they may be an integrated housing corresponding to multiple components of the drying apparatus 2000. For example, in the embodiments shown in Figures 4 and 5, the lower housing 2700 of the drying apparatus 2000 is an integrated housing, and Figure 6 shows a structural diagram of the integrated lower housing 2700. As shown in Figure 6, the lower housing 2700 is provided with a mounting portion 2710 for mounting a circulation fan 2100, a mounting portion 2720 (i.e., a first mounting portion) for mounting a moisture absorption / dehumidification member 2200, a mounting portion 2730 for mounting a regeneration fan 2400, and a mounting portion 2740 for mounting a condensation module 2600. The upper housing of the drying apparatus 2000 is a separate housing and includes an upper housing 2810 for mounting a circulation fan 2100, an upper housing 2820 for mounting a moisture absorption / dehumidification member 2200, an upper housing 2830 for mounting a condensation module 2600, and so on.

[0074] In some embodiments, as shown in Figures 3 to 5, a plurality of fourth mounting parts 2701 are provided on the lower housing 2700 of the drying device 2000, and a fifth mounting part 2801 is provided on the upper housing 2820. The fourth mounting parts 2701 and the fifth mounting parts 2801 are fixed to the housing 1200 of the wash-and-dry integrated washing machine 1000 with wrap fasteners, thereby achieving the mounting and fixing of the entire drying device 2000. In this embodiment, since there is no direct rigid connection between the drying device 2000 and the clothing storage device 1100, vibrations during the operation of the clothing storage device 1100 are not transmitted to the drying device 2000 (especially the moisture-absorbing and dehumidifying member 2200), thereby improving the stability and reliability of the drying device 2000.

[0075] In some embodiments, as shown in Figures 2 and 5, the first air outlet 2902 communicates with the air outlet duct 1300 of the garment storage device 1100 via a flexible tube (e.g., corrugated hose) 2903. In some embodiments, the air outlet duct 1300 is provided with a filter (e.g., a filter mesh) for filtering out dirt and clothing lint. Furthermore, the connecting member 1400 communicates with the air inlet duct of the garment storage device 1100 via a flexible tube (not shown in Figures 2 and 5). This prevents vibrations from the garment storage device 1100 from being transmitted to the drying device 2000 (particularly the dehumidifying and absorbing member 2200), thereby improving the stability and reliability of the drying device 2000.

[0076] In some embodiments, as shown in Figures 4 and 5, the components of the drying apparatus 2000 (including the circulation fan 2100, moisture absorption / dehumidification member 2200, moisture absorption / dehumidification turntable drive unit 2300, regeneration fan 2400, heating module 2500, condensation module 2600, etc.) are arranged horizontally, and the rotation axes of the rotating members (including the circulation fan 2100, moisture absorption / dehumidification member 2200, moisture absorption / dehumidification turntable drive unit 2300, and regeneration fan 2400) are substantially parallel and substantially perpendicular to the rotation axes of the upper housing of the washer-dryer integrated washing machine 1000 and the clothing storage device 1100. According to this embodiment, the height of the washer-dryer integrated washing machine 1000 can be reduced to the greatest extent possible, saving space.

[0077] Under the operation of the circulation fan 2100, a circulating airflow is formed between the moisture absorption passage and the inner cylinder. As shown in Figure 7, under the operation of the circulation fan 2100, the airflow in the inner cylinder sequentially passes through the inner cylinder's air outlet duct (which has a built-in filter) and the flexible tube 2903 and enters the first air outlet 2902, i.e., the air inlet of the circulation fan 2100 (indicated by arrow A). The airflow flows out from the air outlet of the circulation fan 2100 to the underside of the moisture absorption and dehumidification turntable 2201 (indicated by arrow B), passes through the moisture absorption and dehumidification turntable 2201 and reaches the upper side of the moisture absorption and dehumidification turntable 2201 (indicated by arrow C), flows through the upper space of the moisture absorption and dehumidification turntable 2201 (corresponding to the moisture absorption area) (indicated by arrow D), and enters the inner cylinder via the first air inlet 2901 and the connecting member 1400 (indicated by arrow E).

[0078] Under the operation of the regeneration fan 2400, a dehumidifying flow is formed in the regeneration passage. As shown in Figure 8, under the operation of the regeneration fan 2400, the dehumidifying flow enters the air inlet of the regeneration fan 2400 (indicated by arrow A), passes through the regeneration fan 2400, and enters the heating module 2500 via the first connecting member 2909 (indicated by arrows B and C). The heating module 2500 is located above the regeneration region of the dehumidifying turntable 2201. After the dehumidifying flow flows into the heating module 2500, it passes from top to bottom through the regeneration region of the dehumidifying turntable 2201 (indicated by arrow D), and then flows into the condensing module 2600 (indicated by arrow E). The air outlet of the housing of the condensing module 2600 (not shown in Figure 8) communicates with the air inlet of the regeneration fan 2400 via the second connecting member 2910, and the regeneration passage forms a closed loop. The dehumidified flow, after being condensed by the condensation module 2600, flows back into the air inlet of the regeneration fan 2400 via the second connecting member 2910 (indicated by arrow A), thereby allowing the dehumidified flow to circulate and flow through the regeneration passage. The closed-loop regeneration passage avoids interaction between the dehumidified flow and the external environment of the wash-dryer integrated washing machine, thereby reducing the impact on the external environment (e.g., the impact on the humidity of the external air).

[0079] Figures 9 and 10 show a three-dimensional view and an exploded view of the second connecting member 2910, respectively. Figure 9 shows a schematic diagram of the fixing method of the condensing module 2600 and the lower housing 2700. As shown in Figure 9, the upper housing 2830 of the condensing module fits with a mounting portion 2740 (i.e., the lower housing of the condensing module) for mounting the condensing module in the lower housing 2700. The upper housing 2830 of the condensing module covers the condensing module 2600, pressing the sealing strip 2920 around the condensing module 2600 downward and sealing and fixing it with the mounting portion 2740. The upper housing 2830 of the condensing module and the mounting portion 2740 form a complete housing for the condensing module 2600, i.e., the condensing module housing. A second air inlet 2633 is formed on the housing of the condensing module 2600, and the airflow heated by the heating module flows through the regeneration area of ​​the dehumidifying turntable 2201 and then enters the condensing module 2600 through the second air inlet 2633. A second air outlet 2631 is further formed in the housing of the condensing module 2600, and the second air outlet 2631 is connected to the air inlet of the regeneration fan 2400 via a second connecting member 2910.

[0080] Figure 10 shows a cross-sectional view of the condensing module housing 2630. As shown in Figure 10, the high-temperature, high-humidity dehumidified flow that has passed through the regeneration region 2908 enters the condensing module housing 2630 via the second air inlet 2633 (indicated by arrow A), and flows out to the second connecting member 2910 from the second air outlet 2631 after being dried by the condensing module 2600 (not shown in Figure 10) (indicated by arrow B) (indicated by arrow C).

[0081] In some embodiments, as shown in Figure 10, a baffle plate 2632 is provided near the second air outlet 2631 on the bottom surface of the condensing module housing 2630. The baffle plate 2632 improves the condensation effect of the condensing module 2600, and the dehumidified flow is thoroughly dried by the condensing module 2600. For example, the baffle plate 2632 prevents the dehumidified flow entering the condensing module housing 2630 from passing through the condensing module 2600 but from flowing out through the gap between the condensing module 2600 and the bottom surface of the condensing module housing 2630, thus preventing the airflow in this area from being condensed and dried.

[0082] As shown in Figure 9, a condensate pipe 2640 is provided in the condensation module 2600 for circulating condensed water. The condensate pipe 2640 further has a water inlet 2610 and a water outlet 2620. The direction indicated by arrow A in Figure 9 is the flow direction of the dehumidified flow in the condensation module 2600.

[0083] According to some embodiments, the condensate pipe 2640 may be provided with sensors for detecting the state of the condensate, such as a temperature sensor or a flow sensor, or an induction sensor may be provided on the outside of the condensate water inlet pipe to detect whether condensate is flowing through the condensate pipe 2640. Based on the state data detected by the sensors, the water flow in the condensate pipe 2640 can be adjusted or an alarm can be issued to ensure the normal operation of the condensate module 2600 and improve the condensation effect. For example, if the temperature sensor detects that the temperature of the condensate is too high, the condensation effect is currently low, so the flow velocity of the condensate can be increased to lower the water temperature and improve the condensation effect. For example, if the flow sensor detects that the flow rate of the condensate is too low, there is a risk of leakage in the condensate pipe 2640, so an alarm message can be issued to prompt the user to inspect or maintain the condensate pipe 2640. Of course, temperature sensors can be provided at the air inlet and / or air outlet of the condensate module housing, and the normal operation of the condensate module can be detected based on the detected temperature value or temperature difference value or the temperature difference between the air inlet and air outlet.

[0084] In some embodiments, as shown in Figure 9, the condensate pipe 2640 may be a serpentine pipe. In the example in Figure 9, the condensate pipe 2640 is arranged to serpentine within the condensation module 2600, thereby increasing the contact area between the dehumidified flow and the condensate pipe 2640, allowing the dehumidified flow to condense sufficiently. As shown in Figure 9, the condensation module 2600 has a first side and a second side that are opposite each other in the direction of the dehumidified flow (see arrow A), with the first side located downstream of the second side. In one example not shown, the water inlet 2610 and water outlet 2620 of the condensate pipe 2640 are both located on the side wall of the condensation module 2600, which connects the first and second sides of the condensation module 2600, with the water inlet 2610 and water outlet 2620 closer to the first side than to the second side. In this example, the condensate pipe 2640 extends from the water inlet 2610 along a first zigzag path toward the second side of the condensation module 2600 to a position away from the first side, and from that position extends along a second zigzag path toward the first side to the water outlet 2620. The length of the first zigzag path is greater than the length of the second zigzag path, for example, twice the length of the second zigzag path. Due to the heat dissipation of the dehumidifying flow, the temperature of the condensate gradually rises from the first side to the second side of the condensation module 2600, and conversely, due to the heat absorption of the condensate, the temperature of the dehumidifying flow gradually decreases from the second side to the first side of the condensation module 2600. During the condensation process, a constant temperature difference is maintained between the dehumidifying flow and the condensate, improving the condensation effect, thus making this arrangement advantageous.

[0085] In some embodiments, the drying apparatus 2000 includes a housing, for example, an upper housing and a lower housing. The upper and lower housings cover and secure each component of the drying apparatus 2000, forming the drying apparatus 2000 as an integrated module. The housing includes a lower housing 2700 and an upper housing 2820 that house a dehumidifying turntable 2201, with two partition ribs on the lower housing 2700, a first partition rib 2725-1 and a second partition rib 2725-2 of the lower housing as shown in Figure 6, and similarly, two partition ribs (not shown) on the upper housing 2820. A short shaft 2721 and a housing for mounting the short shaft 2721 are provided at the center of the lower housing 2700, and one partition rib 2725-1 of the lower housing 2700 is set to extend from the inner circumferential wall of the housing to the housing housing. Another partition rib 2725-2 of the lower housing 2700 is set to extend from another position on the inner circumferential wall of the housing to the housing compartment. Since at least two partition ribs do not intersect the short axis 2721, they divide the internal space formed by the docking of the lower housing 2700 and the upper housing 2820 into two spaces, namely a first space and a second space, or a moisture absorption space and a regeneration space, or a moisture absorption area 2907 and a regeneration area 2908. The “first space” described above is understood to be the space formed by the partial inner walls of the lower housing 2700 and the upper housing 2820, the side walls of the first and second partition members facing the moisture absorption regions, and the side walls facing the moisture absorption region 7 generated by the portion where the first and second partition members extend and contact. The “second space” is understood to be the space formed by another partial inner wall of the lower housing, the side walls of the first and second partition members facing the regeneration regions, and the wall of the heating assembly 2500 described below. In some embodiments, the housing is annular in shape, and at least two partition ribs are provided tangentially to the outer circumference of the annular housing.

[0086] At least one third partition member 2726 is further provided at the first mounting portion 2720 of the lower housing 2700. The at least one third partition member 2726 divides the moisture absorption region 2907 into at least two parts, a first moisture absorption region 2907-1 and a second moisture absorption region 2907-2, thereby partitioning the circulating airflow flowing into the moisture absorption region 2907. After the circulating airflow enters the space between the lower housing 2700 and the moisture absorption / dehumidification member 2200 via the circulation fan, it is uniformly divided into at least two parts by the third partition member 2726 (i.e., the amount of airflow in the two parts is substantially the same), so that much of the circulating airflow flows around the circumference of the moisture absorption / dehumidification member 2200 under the action of centrifugal force, with the airflow becoming smaller closer to the center. According to this embodiment, the moisture absorption efficiency of the moisture absorption / dehumidification member 2200 can be improved, and uniform and stable moisture absorption can be achieved.

[0087] The housing in the above embodiment can accommodate a dehumidifying turntable 2201. The internal space of the housing is divided into at least a dehumidifying space 2907 and a dehumidifying space 2908. When the dehumidifying turntable 2201 rotates into the dehumidifying space 2907, it performs a dehumidifying function. When the dehumidifying turntable 2201 rotates into the dehumidifying space 2908, it performs a dehumidifying function.

[0088] In one embodiment, a heating module 2500 covers at least a portion of the dehumidification space 2908 and is used to heat the dehumidification space 2908 or at least a portion of the dehumidifying turntable 2201 located in the dehumidification space 2908. A condensing module 2600 is provided downstream of the dehumidification space 2908 and is used to condense the airflow flowing out of the dehumidification space 2908.

[0089] The following describes the processing steps of the garment processing device.

[0090] The garment processing device performs an operation that includes one or more of the following: a washing operation and a drying operation. The washing operation may include a washing stage, a rinsing stage and a spin-drying stage. The washing stage may include a first wash and / or a second wash. The rinsing stage may include a first rinse and / or a second rinse (final rinse). The spin-drying stage may include a first spin-dry (room temperature spin-drying) and / or a second spin-dry (heat spin-drying).

[0091] The drying process may include a preheating step, a heat drying step, and a cooling step.

[0092] The preheating stage is used to heat the dehumidifying turntable 2201 in the drying module to improve the dehumidification and absorption efficiency of the turntable 2201. When the humid airflow in the garment storage device 1100 is circulated to the dehumidifying turntable 2201, it is necessary to maintain a certain temperature in order to achieve dehumidification and absorption. There may be overlapping time between the preheating stage and the dewatering stage, that is, the preheating stage may be started before the end of the dewatering stage. If there is a second dewatering, the heating module 2500 starts operating a little earlier, and the time of the preheating stage is slightly shorter. That is, if there is a second dewatering, part of the heating process of the preheating stage is performed prior to the second dewatering.

[0093] The heating and drying stage is used to heat and dry the clothes in the garment storage device 1100. The humid airflow in the garment storage device 1100 flows continuously to the dehumidifying turntable 2201, which absorbs moisture from the humid airflow and transports the dried airflow to the garment storage device 1100 until the heating and drying is complete. During the heating and drying stage, the garment processing device is in a stable operation phase. Stable operation is mainly reflected in the fact that the temperature difference between the temperature near the first airflow outlet (temperature inside the garment storage device 1100) and the temperature near the air inlet of the garment storage device 1100 is within a stable range of change. For example, in the garment processing device, the temperature difference between the temperature near the first airflow outlet (or temperature inside the garment storage device 1100) and the temperature near the air inlet of the garment storage device 1100 is in the temperature range of 18 to 30°C.

[0094] Temperature detection near the first air outlet may be set to detect one or more temperature points in the temperature field near the first air outlet. Temperature detection inside the clothing storage device 1100 may be set to detect one or more temperature points in the temperature field inside the clothing storage device 1100. Temperature detection near the air inlet of the clothing storage device 1100 may be set to detect one or more temperature points in the temperature field near the first air outlet.

[0095] The cooling stage cools the clothes in the clothing storage device 1100, ensuring that the clothes in the clothing storage device 1100 have an appropriate removal temperature and that the dried clothes have a good feel.

[0096] If the process for determining whether drying is complete is inaccurate during the drying process, there is a risk of stopping the drying process prematurely even though the clothes are still wet, or continuing to heat the clothes at a high temperature even though they are already dry, potentially causing irreversible damage to the clothes.

[0097] In one embodiment, the present application provides a method for controlling a garment processing device. The operation of the garment processing device includes at least a drying operation. The drying operation further includes a heating drying step and a cooling step.

[0098] When the heating module 2500 in the drying apparatus 2000 is operating, the temperature and / or humidity near the first air outlet is detected. The operating power of the heating module 2500 may be dynamically adjusted or it may operate at a fixed power. When detecting the temperature and / or humidity near the first air outlet, a temperature sensor and / or humidity sensor may be provided in the air outlet passage of the first air outlet (they may be provided on the surface of the air outlet passage or embedded inside the air outlet passage).

[0099] When the rate of temperature change near the first air outlet is greater than a first temperature rate of change threshold and / or the rate of humidity change near the first air outlet is less than a first humidity rate of change threshold, it is determined that the heating and drying stage is complete, the system moves to the cooling stage, and the heating module 2500 in the drying apparatus 2000 is turned off. In one embodiment, only the temperature near the first air outlet is detected, and it is determined whether the heating and drying stage is complete depending on whether the rate of temperature change reaches a first temperature rate of change threshold. In another embodiment, only the humidity near the first air outlet is detected, and it is determined whether the heating and drying stage is complete (whether to turn off the heating module 2500 in the drying apparatus 2000) depending on whether the rate of humidity change reaches a first humidity rate of change threshold. In yet another embodiment, the temperature near the first air outlet and the humidity near the first air outlet are detected simultaneously, and it is determined whether the heating and drying stage is complete (whether to turn off the heating module 2500 in the drying apparatus 2000) depending on whether the rate of temperature change and the rate of humidity change reach a first temperature rate of change threshold and a first humidity rate of change threshold.

[0100] This embodiment provides a method for determining whether the heating and drying stage is complete, enabling more timely and accurate determination of the completion of the heating and drying stage, and promptly turning off the heating module 2500. This avoids situations where the heating module 2500 is stopped even though the clothes are not yet dry, and prevents irreversible damage to the clothes due to excessive heating and drying.

[0101] In one embodiment, the rate of temperature change and the rate of humidity change are calculated by the following formulas: Temperature change rate = (Current temperature - Previous temperature) / Time difference between two temperature measurements. Humidity change rate = (Current humidity - Previous humidity) / Time difference between two humidity samplings.

[0102] Specifically, the temperature detected near the first airflow outlet is used to calculate the rate of temperature change near the first airflow outlet. The humidity detected near the first airflow outlet is used to calculate the rate of humidity change near the first airflow outlet.

[0103] In this embodiment, the range of values ​​for the first temperature change rate threshold and the first humidity change rate threshold varies depending on the structural setup of the garment processing device. In one embodiment, the first temperature change rate threshold is set to 3°C / min, and the first humidity change rate threshold is set to 5%RH / min. In another embodiment, the first temperature change rate threshold is set to 1°C / min to 6°C / min, and the first humidity change rate threshold is set to 3%RH / min to 10%RH / min.

[0104] In one embodiment, after the heating module 2500 in the drying apparatus 2000 is turned off, the dehumidifying turntable drive unit 2300 continues to operate for a first period. When the heating and drying stage is completed, the heating module 2500 stops operating, but the dehumidifying turntable drive unit 2300 does not stop operating and continues to operate for a first period. The length of the first period may be set by the user, or it may be set according to the specific circumstances of different drying operations, or the dehumidifying turntable drive unit 2300 may be turned off after the cooling stage is completed.

[0105] In this embodiment, once the heating and drying stage is complete, the operation of the heating module 2500 stops, allowing the drying apparatus 2000 to quickly transition to the cooling stage of the drying operation. Since the operation of the moisture absorption and dehumidification turntable drive unit 2300 is not stopped, the moisture absorption and dehumidification turntable 2201 continues to be driven to rotate, allowing the residual heat from the heating module 2500 to be quickly released, the high-temperature airflow to be quickly cooled, and the cooling stage time to be shortened.

[0106] In one embodiment, during the preheating stage, the dehumidifying turntable 2201 is activated first before the heating module 2500 is started. This allows the dehumidifying turntable 2201 to be heated more uniformly, preventing the heating module 2500 from heating a specific location on the dehumidifying turntable 2201 for an extended period and causing drying burns.

[0107] In one embodiment, once the heating and drying stage is complete, the circulation fan 2100 continues to operate, and the regeneration fan 2400 continues to operate at a higher power.

[0108] In this embodiment, when the heating and drying stage is completed, the circulation fan 2100 continues to operate to form a circulating airflow passing between the moisture absorption areas of the garment storage device 1100 and the dryer 2000, thereby achieving airflow circulation between the garment storage device 1100 and the dryer 2000 and accelerating the cooling rate of the clothes in the garment storage device 1100. On the other hand, the regeneration fan 2400 operates at a higher power to form a regenerating airflow passing through the dehumidified space, transporting more dry regenerating airflow into the dehumidified space, carrying away and discharging the high-temperature humid airflow generated in the dehumidified space, and accelerating the cooling rate of the clothes in the garment storage device 1100. The inlet air for the regeneration fan 2400 can come from the atmosphere or the condensation module 2600.

[0109] In one embodiment, if the temperature near the first air outlet is equal to or greater than a first abnormal temperature value, it is determined that there is a drying operation abnormality, and an alarm signal for the drying operation abnormality is issued. For example, the normal temperature near the first air outlet may be set to 53±5℃ (e.g., 50℃, 53℃, 55℃, 57℃, or 58℃), and the first abnormal temperature value may be set to 60℃. The normal temperature near the first air outlet is a single temperature point in the cross-sectional temperature field where the first air outlet is located.

[0110] This embodiment provides a method for determining a drying operation abnormality, which may be a preheating stage abnormality, a heating and drying stage abnormality, or a cooling stage abnormality. Failure of the condensing module 2600, failure of the regeneration fan 2400, blockage of the filter line, or formation of a water film on the filter line in the garment processing device may lead to a situation where the temperature near the first air outlet exceeds a first abnormal temperature value (60°C).

[0111] In one embodiment, the condensing module 2600 has a second air inlet and a second air outlet. Airflow flowing out from the dehumidification space 2908 enters the condensing module 2600 via the second air inlet, is condensed by the condensing module 2600, and then enters the heating module 2500 via the second air outlet. The drying operation further includes detecting the temperature near the second air inlet, and terminating the heating and drying stage when the temperature near the second air inlet reaches a first temperature threshold. The first temperature threshold is the normal temperature near the second air inlet during the drying operation, generally set to 70±5°C, and may be set to temperature values ​​such as 68°C, 69°C, 72°C, or 73°C. If the temperature near the second air inlet is above a second abnormal temperature value, it is determined that the drying operation is abnormal. The second abnormal temperature value may be set to 100°C. That is, if the temperature near the second air inlet is 100°C or higher, it is determined that the drying operation is abnormal, and an alarm signal for the drying operation abnormality is issued. An abnormality in the drying operation may be an abnormality in the preheating stage, the heating and drying stage, or the cooling stage. If the condensing module 2600 fails, the regeneration fan 2400 fails, the filter line becomes clogged, or a water film forms on the filter line in the garment processing device, it may lead to a situation where the temperature near the second air inlet exceeds the second abnormal temperature value (100°C).

[0112] In one embodiment, the drying operation further includes detecting the temperature near the second air outlet, and when the temperature near the second air inlet reaches a second temperature threshold, the heating and drying stage ends and the heating module 2500 is turned off. The second temperature threshold is the temperature near the second air outlet when the drying apparatus 2000 is operating normally, and is generally set to 60°C ± 5°C. If the temperature near the second air outlet is above a third abnormal temperature value, it is determined that there is a drying operation abnormality, and an alarm signal for the drying operation abnormality is issued. The third abnormal temperature value may be set to 90°C.

[0113] An abnormality in the drying operation may be an abnormality in the preheating stage, the heating and drying stage, or the cooling stage. If the condensing module 2600 fails, the regeneration fan 2400 fails, the filter line becomes clogged, or a water film forms on the filter line in the garment processing device, it may lead to a situation where the temperature near the second air inlet exceeds the second abnormal temperature value (100°C).

[0114] In this embodiment, the heating and drying stage is determined based on whether the temperature near the second air outlet has reached a second temperature threshold, and based on this, it is determined whether to turn off the heating module 2500. In this embodiment, it is determined whether to issue an alarm signal for the drying operation abnormality by detecting whether the temperature near the second air outlet is above a third abnormal temperature value. The detection result can be fed back to the control system of the garment processing device in a timely manner. The control system of the garment processing device prompts the user to quickly check whether any structural member of the drying device 2000 is malfunctioning.

[0115] In one embodiment, during the drying operation, if the temperature near the first air inlet is lower than a preset minimum temperature near the first air inlet, the operating power of the heating module 2500 is controlled to increase. If the temperature near the first air inlet is equal to or greater than a preset maximum temperature near the first air inlet, the operating power of the heating module 2500 is controlled to decrease.

[0116] This embodiment provides a dynamic heating method during a drying operation. The preset minimum temperature value near the first airflow inlet may be set to 60°C to 70°C, and the preset maximum temperature value near the first airflow inlet may be set to 75°C to 80°C. For example, in one embodiment, if the temperature near the first airflow inlet is lower than the preset minimum temperature value of 65°C near the first airflow inlet, the operating power of the heating module 2500 is controlled to increase. If the temperature near the first airflow inlet is 78°C or higher than the preset maximum temperature value near the first airflow inlet, the operating power of the heating module 2500 is controlled to decrease.

[0117] In one embodiment, the heating and drying step includes controlling the heating module 2500 to fluctuate within a preset heating power range and controlling the temperature near the first airflow inlet to within a preset temperature range. In one embodiment, the heating module 2500 fluctuates within a preset heating power range of 400W to 1600W. In one embodiment, the heating module 2500 fluctuates within a preset heating power range of 600W to 1400W and controls the temperature near the first airflow inlet to within a preset temperature range of 60°C to 80°C. In one embodiment, the temperature near the first airflow inlet is within a preset temperature range of 70°C to 75°C. In this embodiment, the heating module 2500 may operate between 600W and 1400W in the form of a sine wave, square wave, sawtooth wave, etc.

[0118] In one embodiment, the preset heating power is the power between a first preset heating power and a second preset heating power, and the heating module 2500 fluctuates in the form of a rectangular wave between the first and second heating powers. In one embodiment, the first heating power is 400W to 800W, and the second preset heating power is 1200W to 1600W.

[0119] For example, in one embodiment, the heating module 2500 operates at an operating power of 580W for a certain period of time. If the temperature near the first airflow inlet is lower than a preset minimum temperature of 63°C near the first airflow inlet, the operating power of the heating module 2500 is controlled to increase, for example, to 1300W for a certain period of time. If the temperature near the first airflow inlet is 75°C or higher, the operating power of the heating module 2500 is controlled to decrease, for example, to continue operating at 580W for a certain period of time. In this embodiment, the heating module 2500 operates at 580W for a certain period of time, at 1300W for a certain period of time, and continues to operate at 580W for a certain period of time, and these three operating times may or may not be equal.

[0120] In one embodiment, during the heating and drying stage, the heating module 2500 is controlled to operate variably within a preset power range of 400W to 1600W. In another embodiment, the heating module 2500 variates according to a square wave within a preset heating power range of 600W to 1400W. The maximum value of the square wave is 1400W, and the minimum value is 600W. The square wave may be an equiperipheral square wave or an unequal-period square wave.

[0121] In the embodiments relating to the adjustment of heating power for the operation of the heating module 2500 described above, the temperature near the first airflow inlet is maintained at a constant level of 60°C to 80°C as much as possible (in some embodiments, the temperature near the first airflow inlet is maintained at 70°C to 75°C as much as possible), and at the same time, the dehumidifying turntable 2201 in the regeneration region has high regeneration efficiency. Specifically, when the heating module 2500 operates with high heating power (e.g., 1400W), the temperature of the dehumidifying turntable 2201 in the regeneration region and the temperature of the dehumidifying flow can be increased, and the dehumidifying turntable 2201 in the regeneration region has high regeneration efficiency. When the heating module 2500 operates with low heating power (e.g., 600W), the temperature of the dehumidifying turntable 2201 in the regeneration region and the temperature of the dehumidifying flow can be decreased, and at the same time, the regeneration efficiency of the dehumidifying turntable 2201 in the regeneration region can be reduced to some extent (however, it can be maintained within a certain regeneration efficiency range, and the regeneration efficiency does not decrease significantly). The heating module 2500 can maintain the temperature inside the garment storage device 1100 or the temperature near the first air inlet throughout the drying operation by fluctuating between high and low heating power, while also balancing the regeneration efficiency of the dehumidifying turntable 2201.

[0122] In one embodiment, the garment processing device comprises at least a garment storage device 1100, a dryer 2000, a drum inlet conduit, a first temperature detection unit, and a control module. The heating module 2500 is electrically connected to the control module. The first temperature detection unit is located in the drum inlet conduit near the air inlet and is used to detect the temperature of the airflow entering the garment storage device 1100 and transmit it to the control module. The drum inlet conduit (i.e., the air inlet duct of the garment storage device 1100) connects an air outlet (first air outlet 2902 shown in Figure 5) provided in the housing to the air inlet (first airflow inlet) of the garment storage device.

[0123] The operation of the garment processing device includes at least a drying operation, during which the heating module 2500 operates within a preset heating power range. The control module adjusts the operating power of the heating module 2500 based on data from the first temperature sensing unit.

[0124] In one embodiment, the heating module 2500 includes at least two temperature sensors. The at least two temperature sensors are used to detect the temperature of the airflow entering the garment storage device 1100. The first temperature sensor is used to detect whether the temperature of the airflow entering the garment storage device 1100 has reached 180°C. The second temperature sensor is used to detect whether the temperature of the airflow entering the garment storage device 1100 has reached 200°C. When the temperature of the airflow entering the garment storage device 1100 reaches 180°C, an alarm signal for a drying operation abnormality is issued and the heating module 2500 is shut down. When the temperature of the airflow entering the garment storage device 1100 reaches 200°C, the power is cut off.

[0125] In one embodiment, the control module adjusts the operating power of the heating module 2500 based on data from a first temperature detection unit, and if the first temperature detection unit detects that the temperature of the airflow entering the garment storage device 1100 is lower than the minimum drum inlet temperature, the control module controls the operating power of the heating module 2500 to increase.

[0126] If the first temperature detection unit detects that the temperature of the airflow entering the garment storage device 1100 is greater than the maximum drum inlet temperature, the control module controls the heating module 2500 to reduce its operating power.

[0127] In one embodiment, the minimum drum inlet temperature is 60°C to 70°C, and may be set to, for example, 63°C, 65°C, 67°C, 68°C, 69°C, or 70°C. The maximum drum inlet temperature is 75°C to 80°C, and may be set to, for example, 75°C, 76°C, 78°C, 79°C, or 80°C.

[0128] In one embodiment, the regeneration fan 2400 and the circulation fan 2100 are kept running at a constant power during the drying operation.

[0129] In one embodiment, the cooling phase includes controlling the heating module 2500 to stop heating; controlling the power of the circulation fan 2100 and / or the regeneration fan 2400 to increase; determining that the cooling phase is complete and controlling the circulation fan 2100 and / or the regeneration fan 2400 to stop operating when the temperature near the first air inlet is less than a fourth temperature threshold and / or the temperature near the first air outlet is less than a fifth temperature threshold. The specific fourth temperature threshold may be set to 50-65°C. For example, the fourth temperature threshold may be set to 53°C, 58°C, 62°C, or 65°C. The temperature near the first air inlet can be understood as the temperature at any point in the temperature field near the air inlet. In this embodiment, heating and drying are no longer required in the cooling phase, so the heating module 2500 is controlled to stop heating. At this point, further cooling is required, so the circulation fan 2100 and the regeneration fan 2400 operate at increased power. In this embodiment, when the temperature near the first airflow inlet is lower than the fourth temperature threshold, it is possible to determine in a timely manner whether the cooling stage has been completed, thereby saving the power consumption required for the operation of the device.

[0130] In one embodiment, the cooling phase includes controlling the heating module 2500 to stop heating; controlling the power of the circulation fan 2100 and / or the regeneration fan 2400 to increase; and determining that the cooling phase is complete when the temperature near the first air outlet is lower than a fifth temperature threshold. The fifth temperature threshold may be ambient temperature or may change according to seasonal changes; for example, the fifth temperature threshold may be set to 5-15°C in spring and autumn, 15-35°C in summer, and 0-10°C in winter. The specific fifth temperature threshold may be preset or continuously modified during operation, thereby adjusting the fifth temperature threshold to an optimal temperature value, accurately determining whether the cooling phase is complete, and achieving the objective of saving power consumption required for device operation.

[0131] In any of the above embodiments, when it is determined that the cooling stage is complete, the operation of the circulation fan 2100 and the regeneration fan 2400 is controlled to stop. If the drying operation is completed at this point and there are no other operations, the entire garment processing device may be turned off.

[0132] In one embodiment, the present application provides a method for controlling a garment processing device, the operation of which includes a dewatering step.

[0133] The dewatering stage includes at least a first dewatering. After the first dewatering is completed, the weight of the clothes in the clothes storage device 1100 is obtained. It is determined whether the weight is less than a preset weight threshold. If the weight is less than the preset weight threshold, the second dewatering is not performed. Existing clothes dryers may have a second dewatering (thermal dewatering) process, but the procedure / capacity of that thermal dewatering is fixed and it is not possible to intelligently select whether thermal dewatering is necessary in the current process. In this embodiment, a step is provided to determine the weight of the clothes after the first thermal dewatering is completed, and if the weight is less than a preset weight threshold, the second dewatering is not performed, thus shortening the clothes processing time and saving some energy while ensuring the effectiveness of the clothes processing.

[0134] If the weight is above a preset weight threshold, a second dewatering is performed, and the heating module 2500 is turned on before the second dewatering. In this step, the second dewatering is a thermal dewatering process, and the temperatures of all stages of the second dewatering are not all equal. In one embodiment, the second dewatering process may be set to occur after the temperature inside the garment storage device 1100 or the temperature near the first air outlet has reached a preset temperature. In another embodiment, the heating module 2500 may be turned on, i.e., the second dewatering is performed, after the first dewatering is completed.

[0135] In one embodiment, during the first and / or second spin-drying cycles, the operating stages of the garment storage device 1100 include at least the following: an operating stage with a first operating power (eccentric) and an operating stage with a second operating power (main spin-drying), wherein the first operating power is smaller than the second operating power. Here, the first and second operating powers are the driving powers of the inner cylinder, i.e., the driving powers of the inner cylinder drive motor.

[0136] If a second dehydration cycle is not performed, the heating module 2500 is controlled to operate at the first heating power after the second operating power phase of the first dehydration cycle has finished.

[0137] In this embodiment, controlling the heating module 2500 to operate at a first heating power may be considered as a second dehydration (thermal dehydration) step, or as part of the preheating stage during the drying operation, and turning on the heating module 2500 during the dehydration stage can save the time required for drying. The specific first heating power may be the maximum heating power of the heating module 2500.

[0138] In one embodiment, when the second dewatering is performed, the heating module 2500 is controlled to operate at the second heating power after the operation phase of the second operating power of the first dewatering is completed, and the second dewatering is a dewatering operation after the temperature inside the garment storage device 1100 or the temperature at the first air outlet has reached the sixth temperature threshold. The second heating power is less than the first heating power and may be set to, for example, 1000W, 1100W or other power values. The second heating power may also be equal to the first heating power and may be set to, for example, 1200W, 1600W. For example, both the second and first heating powers are raised to full power, and after reaching a certain temperature, the power of the heating module 2500 is reduced.

[0139] In one embodiment, when the temperature inside the clothing storage device 1100 or the temperature near the first air outlet reaches a sixth temperature threshold, the heating module 2500 is operated with a third heating power, and the control motor of the clothing storage device 1100 is controlled to operate with a second operating power (the second operating power is greater than the first operating power), and the third heating power is less than the second heating power. The sixth temperature threshold may be set to 45°C ± 5°C.

[0140] In this embodiment, on the one hand, when the temperature inside the garment storage device 1100 or the temperature near the first air outlet reaches the sixth temperature threshold, the efficiency of thermal dewatering is high, and on the other hand, the second operating power is high, and by appropriately reducing the heating power (the third heating power is smaller than the second heating power), the operating power of the entire garment storage device can be secured and the service life of the garment storage device can be extended.

[0141] In one embodiment, after the operation phase of the second operating power of the second dewatering is completed, the heating module 2500 is controlled to operate at a fourth heating power. The fourth heating power is greater than the third heating power. In this embodiment, the fourth heating power may be the full power of the heating module 2500, and by operating the heating module 2500 at a high heating power, the time of the preheating phase during the drying operation can be shortened.

[0142] In one embodiment, the system is controlled to start at least the regeneration fan 2400 and / or the dehumidifying turntable drive unit 2300 before the heating module 2500 starts. Alternatively, the system is controlled to start at least the regeneration fan 2400 and / or the dehumidifying turntable drive unit 2300 before the power of the heating module 2500 reaches a first threshold power. Alternatively, the system is controlled to start at least the regeneration fan 2400 and / or the dehumidifying turntable drive unit 2300 before the heating module 2500 starts up for a first preset time. Alternatively, the system is controlled to start at least the regeneration fan 2400 and / or the dehumidifying turntable drive unit 2300 before the turntable temperature of the dehumidifying turntable 2201 reaches a third temperature threshold. The first threshold power may be set to 400W to 800W. The first threshold power is less than or equal to the low power during normal operation of the heating module 2500 (in the above embodiment, the heating module 2500 fluctuates within a preset heating power range of 400W to 1600W, and here the first threshold power may be less than or equal to the minimum power value within the preset heating power range). The first preset time is less than or equal to the time it takes for the heating power to reach the first threshold power. For example, the first preset time may be set to 10 to 20 minutes, for example, 15 minutes. The third temperature threshold is 180°C or less.

[0143] In this embodiment, three startup timings for the regeneration fan 2400 and / or the dehumidifying turntable drive unit 2300 are provided, and the method for determining these three startup timings can be applied to different garment processing devices. Specifically, by controlling the startup of at least the regeneration fan 2400 and / or the dehumidifying turntable drive unit 2300 before the operation of the heating module 2500, it is possible to avoid the heating module 2500 heating the fixed position of the dehumidifying turntable 2201, thereby reducing damage to the dehumidifying turntable 2201 and extending its service life. By controlling the regeneration fan 2400 and / or the dehumidifying turntable drive unit 2300 to start before the power of the heating module 2500 reaches a first threshold power or before the heating module 2500 starts for a first preset time, and by controlling the regeneration fan 2400 and / or the dehumidifying turntable drive unit 2300 to start before the turntable temperature of the dehumidifying turntable 2201 reaches a third temperature threshold, the dehumidifying turntable 2201 can maintain a constant temperature, thereby improving the preheating effect of the preheating stage of the drying operation.

[0144] In one embodiment, the present application further provides a method for controlling a garment processing device, the operation of which includes a drying operation. The drying operation includes a heating drying step and a cooling step.

[0145] The operation of the cooling phase includes at least the following: S1: Stop heating of the heating module 2500 and control the operation of the circulation fan 2100 and / or the regeneration fan 2400 and / or the dehumidifying turntable drive unit 2300. S2: Detect the temperature near the first air inlet and the temperature near the first air outlet. S3: If the temperature near the first air inlet is less than the fourth temperature threshold and / or the temperature near the first air outlet is less than the fifth temperature threshold, control the operation of the circulation fan 2100, the regeneration fan 2400 and the dehumidifying turntable drive unit 2300 to stop.

[0146] In this embodiment, when the temperature near the first airflow inlet is lower than the fourth temperature threshold and / or the temperature near the first airflow outlet is lower than the fifth temperature threshold, it is determined that the cooling stage has ended, and the operation of the circulation fan 2100, the regeneration fan 2400, and the dehumidifying turntable drive unit 2300 is controlled to stop. The specific fourth temperature threshold may be set to 50-65°C, for example, 55°C, 58°C, 60°C, 63°C, 65°C, etc. The fifth temperature threshold may be ambient temperature, or it may change according to the season. For example, the fifth temperature threshold may be set to 5-15°C in spring and autumn, 15-35°C in summer, and 0-10°C in winter.

[0147] In this embodiment, when the temperature near the first airflow inlet is less than the fourth temperature threshold, or the temperature near the first airflow outlet is less than the fifth temperature threshold, or when the temperature values ​​near the first airflow inlet and the temperature values ​​near the first airflow outlet simultaneously reach the corresponding threshold temperatures, it is determined that the cooling stage has ended, and the operation of the circulation fan 2100, the regeneration fan 2400, and the dehumidifying turntable drive unit 2300 is controlled to stop.

[0148] In one embodiment, in step S1, the power of the circulation fan 2100 is increased to a third circulation power, and / or the power of the regeneration fan 2400 is increased to a third regeneration power. In this embodiment, both the third circulation power and the third regeneration power are maximum power. For example, the third circulation power may be set in the range of 80W to 90W. The third regeneration power may be set in the range of 20W to 30W. In one embodiment, the circulation fan 2100 is operated with increased power of 90W, and / or the regeneration fan 2400 is operated with increased power of 30W.

[0149] In one embodiment, the present application further provides a method for controlling a garment processing device, the operation of which includes a washing operation and a drying operation.

[0150] The heating module 2500 is controlled to start before the washing operation is completed, or before the drying operation begins. At least one stage after the washing operation is completed, the heating module 2500 is controlled to operate variably within a preset heating power range.

[0151] In this embodiment, by activating the heating module 2500 before the washing operation is completed, the garment storage device 1100 can be preheated earlier, thereby shortening the subsequent drying operation time, particularly the time of the preheating stage of the drying operation. In at least one stage after the washing operation is completed (e.g., the heating and drying stage of the drying operation), the heating module 2500 is controlled to operate variably within a preset heating power range (e.g., a preset heating power range of 400W to 1600W). In other stages after the washing operation is completed (e.g., the preheating stage of the drying operation), it mainly operates with a stable heating power, and if a temperature abnormality is detected in other components or if a certain temperature threshold is reached, the heating power of the heating module 2500 is controlled to be reduced.

[0152] In one embodiment, the heating module 2500 can be controlled to start the regeneration fan 2400 and / or the dehumidifying turntable drive unit 2300 first, before starting the heating module 2500, thereby preventing the heating module 2500 from continuously heating a certain part of the dehumidifying turntable 2201.

[0153] In one embodiment, the system is controlled to start at least the regeneration fan 2400 and / or the dehumidifying turntable drive unit 2300 before the heating module 2500 starts. Alternatively, the system is controlled to start at least the regeneration fan 2400 and / or the dehumidifying turntable drive unit 2300 before the power of the heating module 2500 reaches a first threshold power. Alternatively, the system is controlled to start at least the regeneration fan 2400 and / or the dehumidifying turntable drive unit 2300 before the heating module 2500 starts up for a first preset time. Alternatively, the system is controlled to start at least the regeneration fan 2400 and / or the dehumidifying turntable drive unit 2300 before the turntable temperature of the dehumidifying turntable 2201 reaches a third temperature threshold.

[0154] In this embodiment, four timings are provided for the regeneration fan 2400 and / or the dehumidifying turntable drive unit 2300. These four methods for determining the start timings can be applied to different garment processing devices or to different garment processing processes of the same garment processing device. Refer to the description of the embodiment above for details.

[0155] In one embodiment, the present application further provides a method for controlling a garment processing device, the operation of which includes a drying operation. The drying operation includes a preheating stage, a heat-drying stage, and a cooling stage.

[0156] The preheating phase includes at least the following: S10, the dehumidifying turntable drive unit 2300 is started, and the dehumidifying turntable 2201 is rotated at the first rotational speed during the preheating stage.

[0157] S11, the heating module 2500 is activated to heat the dehumidifying turntable 2201 or the dehumidifying space.

[0158] S12, the system controls the regeneration fan 2400 to start before the power of the heating module 2500 reaches a first threshold power, or before the heating module 2500 starts up for a first preset time, or before the temperature of the dehumidified space reaches a third temperature threshold. In this embodiment, the preheating stage of the drying operation is as follows: first, the dehumidifying turntable 2201 is started, then the heating module 2500 is started, and finally the regeneration fan 2400 is started. By starting the dehumidifying turntable 2201 first, it is possible to avoid the dehumidifying turntable 2201 being heated in a fixed position. By starting the regeneration fan 2400 before the three situations in S12 occur, on the one hand, the heat generated by the heating module 2500 can be sufficiently circulated within the clothing storage device 1100 to heat the clothes, and on the other hand, the actual power consumption of the device can be reduced and energy can be saved.

[0159] In one embodiment, the present application further provides a method for controlling a garment processing device, the operation of which includes a drying operation.

[0160] The drying process includes a preheating stage, a heat drying stage, and a cooling stage.

[0161] S20, the regeneration fan 2400 is started. S21, the heating module 2500 is started to heat the dehumidifying turntable 2201 or the dehumidifying space. S22, the dehumidifying turntable 2201 is controlled to start before the power of the heating module 2500 reaches a first threshold power, or before the heating module 2500 is started for a first preset time, or before the temperature of the dehumidifying space reaches a third temperature threshold.

[0162] In this embodiment, the preheating stage of the drying operation is as follows: first, the regeneration fan 2400 is started, then the heating module 2500 is started, and finally the dehumidifying turntable 2201 is started. By starting the regeneration fan 2400 first, a regeneration airflow can be formed in the dehumidified space of the dehumidifying turntable 2201. Next, by starting the heating module 2500, the heat generated by the heating module 2500 is circulated using the regeneration airflow, thereby preventing the dehumidifying turntable 2201 from being heated in a fixed position.

[0163] In one embodiment, the present application further provides a method for controlling a garment processing device, the operation of which includes a drying operation. The drying operation includes a preheating stage, a heat-drying stage, and a cooling stage.

[0164] S30, the heating module 2500 is activated to heat the dehumidifying turntable 2201. S31, the dehumidifying turntable 2201 is activated and the regeneration fan 2400 is activated before the power of the heating module 2500 reaches a first threshold power, or before the heating module 2500 is activated for a first preset time, or before the temperature of the dehumidifying space reaches a third temperature threshold.

[0165] In this embodiment, the preheating stage of the drying operation is as follows: first, the heating module 2500 is started, then the dehumidifying turntable 2201 is started, and finally the regeneration fan 2400 is started. By starting the heating module 2500 first, the dehumidifying turntable 2201 is started before any one of the three conditions in S31 occurs (before the first condition occurs).

[0166] In the three embodiments described above, the third temperature threshold may be set to 160-180°C, for example, 162°C, 167°C, 172°C, 175°C, or 180°C. The first rotational speed is 8-15 rpm. During the heating and drying stage, the rotational speed of the dehumidifying turntable 2201 is reduced. In one embodiment, the dehumidifying turntable 2201 rotates at a second rotational speed. The second rotational speed is 2-8 rpm, and in different embodiments, the second rotational speed may be set to 4 rpm, 5 rpm, 6 rpm, or 7 rpm.

[0167] In one embodiment, the present application provides a method for controlling a garment processing device, the operation of which includes a drying operation. The drying operation includes a preheating stage, a heat-drying stage, and a cooling stage.

[0168] During the preheating phase, the heating module 2500 is activated and operates. Specifically, the heating module 2500 operates at maximum power immediately after activation, and when it is detected that the temperature inside the garment storage device 1100 or the temperature near the first air outlet has reached the sixth temperature threshold (45°C), the heating power of the heating module 2500 is controlled to be reduced. On the one hand, the system temperature of the dryer 2000 can be appropriately adjusted, and on the other hand, the moisture absorption and dehumidification turntable 2201 can be protected, preventing drying burns at a certain point on the moisture absorption and dehumidification turntable 2201 due to high temperatures.

[0169] During the heating and drying phase, the heating module 2500 fluctuates within a preset heating power range (400W to 1600W). During the preheating phase, the heating power of the heating module 2500 is less than or equal to the maximum power value within the preset heating power range. The preset heating power range may be set to 600W to 1400W. The heating module 2500 fluctuates within the preset heating power range according to different waveforms. During fluctuating heating, if it is detected that the temperature inside the clothing storage device 1100 or the temperature threshold temperature near the first air outlet has reached the sixth temperature threshold, the power is reduced and operation is stopped. During the cooling phase, the operation of the heating module 2500 is controlled to stop.

[0170] In this embodiment, the heating module 2500 is provided to operate at different power levels at different stages of the drying operation in order to obtain the highest drying efficiency in the shortest time.

[0171] In one embodiment, during the preheating stage, the regeneration fan 2400 operates with a first regeneration power. During the heating and drying stage, the regeneration fan 2400 operates with a second regeneration power. During the cooling stage, the regeneration fan 2400 operates with a third regeneration power. Here, the first regeneration power is less than or equal to the second regeneration power, and the first regeneration power may be zero. The third regeneration power is greater than the first regeneration power, and the third regeneration power is greater than or equal to the second regeneration power.

[0172] In this embodiment, the second regenerative power may be fixed power or variable power, and the magnitude of the second regenerative power may change in a positive correlation with the fluctuations of the heating module 2500. A positive correlation change is understood to mean that there is a positive correlation in the increasing and decreasing trends of the heating power and the regenerative power, and that the change time has a certain delay. For example, the regenerative power increases after the heating power increases for a certain period of time. The regenerative fan 2400 is designed to operate at different regenerative powers at different stages in order to improve the drying efficiency of the garment processing device.

[0173] In one embodiment, during the preheating stage, the moisture-absorbing and dehumidifying turntable drive unit 2300 rotates at a first rotational speed. During the heating and drying stage, the moisture-absorbing and dehumidifying turntable drive unit 2300 rotates at a second rotational speed. During the cooling stage, the moisture-absorbing and dehumidifying turntable drive unit 2300 rotates at a third rotational speed. Here, the first, second, and third rotational speeds are equal. Alternatively, the first and third rotational speeds are greater than or equal to the second rotational speed. The second rotational speed may be set to 2 to 10 rpm, and in one embodiment, it may be set to 4 to 6 rpm.

[0174] In this embodiment, by setting the rotational speeds of the moisture-absorbing and dehumidifying turntable drive unit 2300 to be equal, or by setting the first rotational speed and the third rotational speed to be equal to or greater than the second rotational speed, the moisture-absorbing and dehumidifying turntable 2201 rotates at an appropriate rotational speed, thereby improving the dehumidification efficiency of the moisture-absorbing and dehumidifying turntable 2201.

[0175] In one embodiment, during the preheating stage, the circulation fan 2100 operates with a first circulation power. During the heating and drying stage, the circulation fan 2100 operates with a second circulation power. During the cooling stage, the circulation fan 2100 operates with a third circulation power. Here, the first and third circulation powers are greater than or equal to the second circulation power. The second circulation power may be a fixed power or a dynamically changing power, and the magnitude of the second circulation power changes in accordance with the power change of the heating module 2500, that is, it changes in a positive correlation with the change in heating power of the heating module 2500.

[0176] In this embodiment, the circulating fan 2100 has a heating power that matches that of the heating module 2500 and a rotational speed that matches that of the moisture absorption / dehumidification turntable drive unit 2300 during the heating and drying stage, thereby improving the drying efficiency of the drying apparatus 2000.

[0177] In one embodiment, the drying apparatus 2000 further includes a condensing module 2600 located on the other side of the dehumidifying space and used to condense the airflow flowing out of the dehumidifying space. The condensing module 2600 is a water-cooled condenser. In at least one stage of the operating process of the garment processing device, the water flow rate is 0.2 to 0.4 L / min. In one embodiment, during the heating and drying and cooling stages of the drying operation, the water flow rate is set to 0.36 L / min.

[0178] In one embodiment, the present application provides a method for controlling a garment processing device. The garment processing device comprises a garment storage device 1100 and a drying device 2000. The operation of the garment processing device includes a drying operation. The drying operation includes a preheating stage, a heat-drying stage, and a cooling stage.

[0179] At the start of the preheating stage, the heating module 2500 starts up and operates, and if it detects that the temperature inside the clothing storage device 1100 or the temperature threshold temperature near the first air outlet has reached the sixth temperature threshold (which may be set to 45°C), it controls the heating module 2500 to operate at reduced heating power. The regeneration fan 2400 operates at the first regeneration power. The dehumidifying turntable drive unit 2300 rotates at the first rotational speed. The circulation fan 2100 operates at the first circulation power.

[0180] During the heating and drying stage, the heating module 2500 fluctuates within a preset heating power range. The regeneration fan 2400 operates at a second regeneration power, or the regeneration fan 2400 changes in a positive correlation with the change in heating power of the heating module 2500, with the second regeneration power being greater than the first regeneration power. The dehumidifying turntable drive unit 2300 rotates at a second rotational speed, which is less than or equal to the first rotational speed. The circulation fan 2100 operates at a second circulation power, or the circulation fan 2100 changes in a positive correlation with the change in heating power of the heating module 2500, with the second circulation power being less than or equal to the first circulation power.

[0181] During the cooling phase, the heating module 2500 is controlled to stop operating. The regeneration fan 2400 operates at a third regeneration power, which is greater than the second regeneration power and greater than the first regeneration power. The dehumidifying turntable drive unit 2300 rotates at a third rotational speed, which is greater than or equal to the second rotational speed. The circulation fan 2100 operates at a third circulation power, which is greater than the second circulation power.

[0182] In this embodiment, a control strategy for the operation of each component of the drying apparatus 2000 is provided during the drying operation in order to maximize the drying efficiency of the drying apparatus 2000. In this embodiment, the specific values ​​of each parameter can be found by referring to the description of any one of the embodiments described above.

[0183] In one specific embodiment, referring to Figure 13, the preheating stage heating module initially operates for a first stage time with a heating power of 1400W. When the temperature inside the garment storage device 1100 or the temperature near the first air outlet reaches the sixth temperature threshold (45°C ± 5°C), the heating power of the heating module is reduced to 600W. During the heating and drying stage, the heating module operates with a heating power of 600W to 1400W. During the cooling stage, the heating module stops operating (operating power is 0).

[0184] During the first stage of the preheating phase, the internal cylinder drive motor operates at a rotational speed of 40-100 rpm. When the heating power of the heating module 2500 decreases (when the temperature inside the garment storage device 1100 or the temperature near the first air outlet reaches the sixth temperature threshold of 45°C ± 5°C), the internal cylinder drive motor increases its rotational speed, reaching a maximum rotational speed of 1400 rpm (the process in which the internal cylinder drive motor operates at a high rotational speed is the second dewatering process). During the heating and drying phase and the cooling phase, the internal cylinder drive motor operates at a rotational speed of 40-100 rpm.

[0185] During the preheating, heating and drying, and cooling stages, the dehumidifying turntable drive unit 2300 drives the dehumidifying turntable 2201 to operate at a rotational speed of 2 to 10 rpm.

[0186] During the preheating and heating / drying phases, the operating power of the circulation fan is set to a range of 30-90W, and the rotation speed of the circulation fan is set to 3800rpm-4000rpm. During the cooling phase, the circulation fan operates at a rotation speed of 4000rpm-5600rpm.

[0187] During the preheating and heating / drying stages, the operating power of the regeneration fan is set to a range of 10-30W, and the rotation speed of the regeneration fan is set to 3700rpm-3900rpm. During the cooling stage, the rotation speed of the regeneration fan is 3900rpm-4100rpm.

[0188] In the specific embodiment described above, the most important heating and drying stage during the drying operation can be set to 100-110 minutes, thereby shortening the drying time and improving drying efficiency.
